1.	Two identical long, solid cylinders are used to conduct heat from temp `T_(1)` to Temp `T_(2)`. Originally the cylinders are connected in series and the rate of heat transfer is H. If the cylinders are connected in parallel then the rate of heat transer would be:A. `H//4`B. `2H`C. `4H`D. `8H`
Answer» Correct Answer - C Initially effective resistance = `2R` . In parallel effective resistance =`R/2` . It has reduced by a factor of `1//4` so rate of heat transfer would be increased by a factor of 4, keeping other parameters same.
